There is a problem with the automatic shutoff. There may be carbon fines or debris in it. When the shutoff is trying to close it will have a chirping or light honking noise. Try running all the water out of the tank Make sure you clean and sanitize the filter housings when changing filters.
Here is a link for Culligan RO manuals.

Absolutely! This is a common problem when filters have not been changed at regular intervals, improper method of changing filters, contaminating the housings and filters introduces bacteria into the system and there is no better place for it to live and prosper. Any drinking water system needs regular sanitizing to prevent the buildup of bacteria. If the drain is not properly plumbed in with an air gap, cross contamination can occur from the the DWV line also.
This system is no longer safe to drink from. The good news is it can be sanitized and filters replaced to get you back in business. www.softenerparts.com sells a sanitizing solution for RO systems and the filters you need also.

Here are the steps to remove your RO system. Put a pan and a couple rags under sink to catch any water that might spill.
1. Label all the lines from RO (with masking tape) to remember where they go.
2. Turn the water off to RO system
3. Run all the water from the RO tank
4. Turn the valve off on RO tank.
5. Remove the line to the RO tank and pull tank out.
6. Remove the line to the RO drain.
a. If there is an AIR GAP faucet this line may go there first
b. plug the whole for RO drain or replace the standpipe
7. Remove the product line from RO faucet
8. Remove the water line feeding the RO system.
9. Make sure the valve feeding RO is shut off completely
a. If this valve is a piercing valve you may want to consider replacing the section of copper
plumbing because it will eventually leak if left unused.
10. When re-installing the RO remove old filters, sanitize system and replace with new filters.

The Sediment filter goes in LEFT cartridge
The Block Carbon filter goes in the RIGHT cartridge
The Membrane goes in the CENTER cartridge

Too much pressure in holding tank will not cause leaks in the RO unit. All too much pressure in tank will do is cause low or no product water in RO tank. Older Culligan RO systems (H8, H83, H5) had fittings that used metal locking washers and these can cut the RO line after the RO has been moved around while changing filters. Newer styles (AC30, Water Tower) use quick connect fittings and the RO line may work loose after filter changes and system being moved around under sink.
Turn the incoming water off to RO, turn the water off on RO tank, open the RO faucet to relieve pressure and pull the line off feeding the RO tank, inspect (you may want to cut off a small portion of the line at the filter) check the o-ring and re-install.

I have used numerous sets of Culligan filters and membranes from this on-line supplier and had very good success with them. No issues as with other knock off filters. No I do not work for them.

I prefer to clean the housings out with about a tablespoon of bleach before installing filters. TFC membranes used in almost all RO systems are susceptible to chlorine degradation. So unless you pull all the filters and sanitize the system it is NOT a good idea to add bleach to housing when installing filters. It helps to use latex gloves when changing filters to prevent bacterial contamination from your hands. This is the main reason RO systems need to be sanitized with filter changes.

Sanitizing the reverse osmosis system each time you change filters is a good practice. It is very easy to introduce bacteria into the RO system simply from your hands. I prefer to clean the housings with a tablespoon of bleach and rinse them thoroughly. Most RO systems now have TFC membranes, these membranes are susceptible to chlorine damage so it is important that any bleach not come in contact with the membrane. Changing of the capillary tube should be done about every 3yrs or if any iron is present sooner. It also helps to wear latex gloves when changing filters to prevent introducing bacteria into the RO. If this is done you may get by with sanitizing every other time. Make sure you dump at least 2 tanks of water after installing new filters and sanitizing.

Culligan should have a used filter housing to replace the broken one. I think those housings have a 10 year warranty. I would check your warranty if you are the original owner.
